255.255.255.255: IP Office has used up all the addresses

The Internet is running out of addresses: On Thursday, the last available IP addresses distributed. Because the 4.3 billion possible addresses are not sufficient, now a new standard is introduced. IPv6 provides space for 340 sextillion addresses. All IP addresses of the current standards for data exchange on the Internet are used up.

This is the highest award of Section informed of these measures, the IANA, on Thursday in Miami. The 1980 introduced standard IPv4 allows 4.3 billion addresses - but these have now been exhausted. The last five free blocks of IP addresses were symbolically awarded to representatives of the awarding bodies in the continent.

The last was the head of the European procurement agency Ripe, Axel Pawlik, the IP4 addresses receive in an envelope. But that is no reason to panic: the already distributed to the regional IP registries supplies should be adequate for several months. A new standard is already a done deal: The new IPv6 addresses consist of 128 numbers are possible to be 340 sextillion addresses - as a figure: 340,000,000,000,000,000,000,000,000,000,000,000,000.

That is about the relationship of a tiny water droplet with a diameter of 0.3 millimeters to the entire water resources of the world. This makes it theoretically possible to any computer, any phone and any other device to assign a single IP address for life. To address the related privacy concerns, the new Protocol "Privacy Extensions", which should prevent that a device for a long time to identify the network.

In Windows, this privacy extensions are enabled by default on a Mac or a Linux machine, they need to be established. The change is being prepared for years - but run too slow, warned Bitkom head August-Wilhelm Scheer: "Europe is lagging in the transition to IPv6, Asia and America behind." Few problems and plenty of time for home users are currently in Germany still not all Internet providers to offer its customers Served on the basis of offering IPv6, complained Scheer.

"If European companies are still using the old standard, the customers have their systems and networks in Asia but have switched to IPv6, then they can not properly communicate over the Web," said Bitkom boss. During the forthcoming transition to a new Internet Protocol there should be for home users but few problems.

With special transition techniques the company ensure that customers do not lose that are further on the road with IPv4 technology in the network, their access to the Internet. Major ISPs such as the German Telekom claims to want only the end of 2011 begin to assign IPv6 addresses to private customers.

The operating system must be able to handle the new Internet protocol. Windows Vista and Windows 7 control of the new standard of domestic as well as the current Mac and Linux systems. For Windows XP users have with a few simple repair.
